The present inventfon felates to electronlognetic relayS, of to devfoes fn vvflioh a cuffent f1ov ing in a Winding oonneoted in a first eleotriool circuit causes the operotfon of o SWitoh oonnected in a seoond electrfoo1 offonft.

An obieot of tho pfeSent fnventfon is to pfo vide on ifnpfoveo eleoffonlognetio felay Whfoh is especiany adopted fof fopid ond ffequent operation.

ffnother object of the pfeSent invention is to provide an ifflpfoved eectfoniagnetio felay Which isospociany odapted for use in connection with the contro1 of eleotrioa1 cifouits on airofaftv A further object fS thefefofe to pfovide a lelay in which the size and Wefght of the Struoture is fe duoed to a minimufn.

Another object is fo pfovide an in1proved hinge of pivot struot11fe fo1 the afnlatufe of a felay adapted fof fapid and ffeqoent opefation. A fufther object of the pfeSent invention is to p1'ovide, in a felay adapted fof rapid and frequent opefation, an aTInatufe stTuoture of SIna11 Inass and hence of low ineftia. A sti11 fufthef object iS to pTovide fesilient fneans fof stopping the n10- tion of sI1ch an ofn1ature towafds its fetfaoted position, thefeby pfeventing any tendency of the armatufe to bounce.

A further object is to provide an iInpfoved stop stfucture for liffliting the fnovefnent of a felay arfflatufe tovvard ifS fetfaoted position. A stiH fufther objeot is to oonstruot Suoh a stop of de forfnable Inaterial, So that the spaoing of the relay oontacts Whenthe Winding iS deenergized may be feadny adjusted.

AnotheT object iS to Tovide an iInproved housing ond tefn1ina1 oonnection arrangenoent for an electroInagnetic felay.

Another objeof of the preSent invention iS to pfovide an ifnpfoved felay of the Safne genefa type as that shown and olaimed in 1ny pfiorr Patent No. 2 21,838, issued 1/fay 13, 191.

()ther objeots and advontages of fny invention Wi11 becofne appofent ffon1 a considefation of the appended speciffcation, caiIns, and drawing, in which: v

ffgufe 1 is an elevational view of a Telay eIn bodying oeftoin feotofes of n1y invention,

1efeffing to l 'fgufe 1, thefe is shoWn a relay inoluding o oon Wound on g spoo f l, Whfoh sufrounds a core Inen1ber l2. The oore IneIT1ber l2 is ottached, by any st1ftoble ffleons, to the centef of the poftfon of o U-shaped ffonle IneInber f3, the core nleo1ber l2 and U-sha ed fran1e IneInber l 3 constituting o oore stfuotore having a Winding of ooil ln n1ounted thereon and ooInpriSing two spaced Inognetio nlenlbefs. As Wi11 be late1 noted, an arnlature f2 fs n1ounted on one of theSe spaced fnagnetic fnen1befs for fnovefnent felative to the other.

The con m is thfough Which it trical oifcuif.

panel f, of insuloting nlatefiaL is attached,

l5, to the left upfight poftion of the U-Shaped ffofne member l3. A1So attached to the left upffght of the ffame Inen1bef 3 by fneans of the Tivet l5 iS a Stop fnelnbef ls, of some defoffnoble Inoterfol. Tf1e upper portion of the outside laterol soffooe of the pane1 f iS pfovided vith 3 plufalfty of ohannelS l T, adapted to feceive a coffeSpondfng 11t1fflber of conductor strips lB, each of Whioh ffloy be ffxed in position on the pane1 !2 by o fivet 9.

Bach oondoctor strip lo has its lower end tuIned outwardly and bifuroated to fofn1 a terIninal struotufe 2l Whioh is odapted to fooeive the end of an electrical conductof. The upper end of each contact strip lB is bent of fight angles to the oentra poftion of the strip and oarfies at itS extrefnity a Stationary oontoot 22.

The fight npright of the u-Shaped frame member !3 cafffeS a plafe 23-, vvhfch fnay also be of Te plote 23 may be nxed to the frafne meInber l3 by ony Suitable Ineans, Such as ffvefs 2. BivetS 22 alSo fasten to the upright 2 a pane 25 of insulating InoteriaL Which oafries, by ony suitable nleons, a paif of wing tern1inals 2G.

The lower end of the plote 23 iS bent outwardly, as at 27, and is opeftufed to feoeive a hook on the lower end of 8 tensfon spring 28.

The uppef end of the upHght 2" is bevefed, aS at 3 (See fgufe 3), to pfovide a shafp edge 33 of the fefn1inotfon of the outer suffaoe thefeof.
